Why are session_decode and session_encode needed in php?

Question

PHP

Hello, I recently stumbled upon such a topic as sessions in php, I got interested, and now I think what these methods are for, in terms of use, because the desired session itself is decoded and entered into the $_SESSION super global variable, and saving sessions is also automatically simple replenishment/change of elements inside the given array....

Answer 1

serialize and deserialize session variables.
It is necessary when you restore session from server variables.
